Late the the whole thing, but I have to ask, why would you want to 'Post
to a template' and have all of the validation logic in a <script> tags?

Validation logic can include things like sql calls, calls to remote
sites, etc. This is surely best done in the 'controller' space and
outside of a zpt, which AFAIK are to be used for presentation.

Like I said, I'm late the the whole discussion and zope3 is a very new
thing to me.
